Portable Fire Extinguisher

Handheld extinguisher system or portable fire extinguisher is an essential system that should be equipped inevery types of containment building along with other fire extinguisher equipments that are already available.
The portable fire extinguisher is very important in tackling the starting flames in an attempt to put out the fireat the first stage where the people who face this incident can reach for the fire extinguisher immediately. The
size of the handhled extinguisher is preferably use about 4.5 kg but not more than 18.4 kg because it will be
too heavy and not effeiciently use.
There are many classes of fire extinguisher and each one has different capability in putting out the fire as thefollowing detail:1. Class A is fire that start from typical materials that are flammable such as: wood, fabric, paper, rubbberand plastic.
2. Class B is fire that start from combustible material such as : gas, oil, tint, paint, lacker and cooking gas.
3. Class C is fire that start from electicity materials such as: electricity circuit.
4. Class D is fire that start from materials that can burn such as: magnesium, sodium, Lithium, Potassium
and groups of Chrodium.
• The capability of using the handheld fire extinguisher depend on the clasification of the starting flamesthat is shown in table xx. 3.1.
.
• The method for equiping the fire extinguisher must gaurantee the sufficient amount and put in a spot
where people can easily get access through as required in the table xx. 3.2 and table xx. 3.3

Document Fire Hose System
The fire hose system has 2 systems which are: dry pipe system and wet pipe system that has the following
element:
1. Fire extinguisher water source :-from the public water pipe that has sufficient pressure and amount of water,-from the automatic water pump system.,-from the water pump system authorize by the fire departments,-from the pressure tank,-from the water storage tank
2. Increase water pressure system
Which may be pumping from fire extinguisher water supply that runs by fuel or electricity or
increasing the pressure to allow natural water flow from the high water storage tank. The increasewater pressure system must give pressure to the fire hose at least no less than 4.4 barrel or 44 metersof water.
3. Standing pipe or vertical pipe
This has the size and amount of water flowing depending on the usage of the work and the amount ofstanding pipes (see table)
4. Fire extinguisher hose
There are many size of the fire extinguisher hose which is separate into 3 types according to the users
as following:- Type 1: use by the fire departments and primarily trained personnel in using heavy stream hoseparticularly.
- Type 2: use by the ones that are inside the building until the fire department arrives.
- Type 3: use by the fire departments or those who are inside the building who has experience inusing the heavy stream hose before.
The descriptions on the size of the fire extinguisher lines and tubes are identified in the table.
• For type I and III there must be pressure left at the cap of the hose 4.4 barrel or 44 meter of waterand must have 32liter/second amount of flowings in a 30 minutes time.
• The hose must have a length that can reach the fire incident point at least no less than 10 metersfrom the pipe location. The length is 15 meters, 23 meters and 30 meters. If the building splits
rooms into zone, the amount of the standing pipe or hose connections increases.
• The height of the fire cable box must not be less than 1.5 meter and must set at a spot with no
obsticles and has a indicate sign that can be seen clearly. See the design of the fire hose cabinet in
the table.

Automatic Sprinkler System
The automatic fire extinguisher uses water through sprinkler system, it is an effective systems preventing lossof life and property from fire potential. This system contains the pressure increase system, a fire extinguisher
hose, a retail of the hose with pressure that distribute to the head of the extinguisher hose or the sprinkler.
When a predetermined temperature has been exceeded, the chemical bulb on the sprinkler cap will break anddischarges water. The most common use system is the wet pipe which has water and pressure available in thepipe at all time.
The designing of the sprinkler system depends on the following charateristics: (detail shown in table xx.5.1)
1. Group 1 is the building with light hazard occupancies
2. Group 2 is the building with ordinary Hazard Occupancies
3. Group 3 is the building with extra hazard occupancies• The maximum fire extinguish area of each type of building is shown in table xx.5.2,• The maximum fire extinguish per head and the distance between the sprinkers is shown in table xx. 5.3
and 5.4,• The size for the amount of sprinklers are shown in table xx. 5.5, 5.6 and 5.7,
• The designing of the sprinklers for ceilings with various temperature are shown in table xx. 5.8,
• The radius of the sprinklers, the rate of water flow and the pressure of the size of the common use hose is
12.5 mm which can sprinkle out water at the rate of 80l/minute or 1.33l/second with the pressure that canbe estimate with the unit K factor which is shown in table xx. 5.9.
• The level of water pressure that the water from the sprinkler should be about 11 meter of water of 1 barrel
for the building types in group 1 and 2. For Group 3, there must be a specialist engineer to design andcondider together with the authority due to the building type that has high risk of fire potential.
• The rate of the sprinkler’s water flow for building types in group 1 should be between 30-45 l/second andfor group 2 should be between 42-90l/second. For Group 3, there must be a specialist engineer to designand consider together with the authority due to the building type that has high risk of fire potential.
• The amount of time to put out fire with sprinkler for building types in group 1 should be between 30-60
minutes and in group 2 it should be between 60-120 minutes. For Group 3, there must be a specialist
engineer to design and consider together with the authority due to the building type that has high risk offire potential.

140Standpipe System

The size of each standpipe depends on both the amount and size of the hose line that may use at the same timeand if there aren’t any issue with deviding rooms into sections then the distance between the hose and water
storage can indicated the location of the standpipes by the use of the building areas.
Class I and III of standpipe system
1. A standpipe with height no more than 30m must have the size no less than 100mm
2. A standpipe with height over 30m must have a size at least 150mm
3. A standpipe must have the height no more than 84m. If the building is taller it must design astandpipe system that can distribute weter into zones.
4. In the case of using the standpipe to both a hose system size 65mm and the automatic sprinkler, thestandpipe must have the size of 150mm,
5. In case the setting of the fire extinguisher that distribute water to the area with high floor levelcompiles with the ones distributing to the lower floor level, the distributing pipe of each zone musthave a size over 200mm. For high floor level with more than 2 standpipe shall have a direct
distributing pipe with size no less than 200mm for at least 2 pipes to discharge water to the standpipes.
Class II of standpipe system
1. There are 2 types of hose lines which are: folded flexible hose line hanged inside a cabinet with size
equivalent to 40mm and the rolled suction hose line with size 20mm or 25 mm.
2. The size of the standpipe must be adequate to distribute the water fore at lwast 6.3 l/second.
3. The standpipe sith height no more than 15m must have a size at least 50mm. In case the standpipe
with height no more than 15m, the size should be at least 65mm. Normally, the size of the standpipe
should not be less than 100mm.

Fire Alarm and Detector System
The most common reason to the damage of life and property is from fire accident which happens from notbeing able to evacuate the occupants out of the buidling in time and before knowing there is a fire, it would
already be too late. Therefore, it is neccessary to have a fire alarm to increase the protection to the occupants
and have a heat detector system in addition to qualify the prevention of fire spreading in time as the following
detail:1. fire alarm using hand
Is a device that sends warning by the stimulating of an individual. It is an electric switch that is seen in a
red symbol and easy to comprehend, the reset will be done by the included equipments which are: the keys
which cannot be reset with bare hans. The portable fire alarm must set at a clear location at the entrance orexit of a building with distance between the material no more than 60m, height distance from the groundbetween 1.3-1.5m to allow the disabled people to be able to use it as well.
2. fire alarm using sound
There are many kinds of this type of device such as: ringing, whistle, sirens and through speakers. The
sound of this device must be differetn from tother alarm in the normal situation such as: alarms for end ofwork period, the volume of this type of sound must be louder than the ambience around no less than 15
decibel and the sound in each point must not be less than 65 decibel and no more than 120 decibel. In casethe building is a residential type, the volume of the sound must not be less than 70 decibel to wake theresidence who are sleeping. The amount of time of the alarm must nor be less than 60 seconds. In case theambience has a volume louder than 95 decibel, there should be a fire alarm with lights involve. The heightin setting the fire alarm deive is 2.3m and has a distance from the ceiling no less than 15cm.
3. Fire alarm using lights
It is a device that sends beaming lights to allow the occupants know the incident. This type of device issuitable for lacating in a place with sound louder than 95 decible and at an area that lacks of hearing
capability. Normally, the device will send white light out in a ratio of 1-2 times/second. The fire alarming
device using lights must set in a place to see clearly and covers an area. The distance of this device dependon the brightness of the light but must not be more than 30m. (the detail of the fire alarm process is indicatedin the attachment files)
4. Smoke detector
This is a device that is use to detect the amount of smoke resulting from the burning of a material. Eachdevice has the capability to detect a fire faster than the thermal detector. In some case, a fire incident cancreate smoke without any change in the room temperature (detail of the settings are indicated in theattachment files).
5. Thermal detector
The thermal detector is mostly located in an area with limited space for a smoke detector such as: the car
garage, kitchen and other places thatsmoke happens but not because of a fire incident. In some case, anadditional settingof a thermal detector is located along with the smoke detector to increase the capability ofdetecting a fire. Even so, the thermal detector cannot be a replacement for the smoke dectector particularly
along the fire escape route. (detail of setting indicated in the attachement files)
6. Flow switch
The flow switch is a device that detects in the fire extinguishor system by water. When the water flows dueto the process of the sprinkler pr the hose to put out fire, the flow switch will send signals to the monitor
and sent an alarm to the building occupants.
